Worth understanding the distinction: Eaton's 4623 and 5421 are gear pumps — simple, robust, fixed-displacement units suited to moderate-duty applications. The 72400 is a genuinely different design, a variable-displacement piston pump running at higher pressure (250 bar vs 200 bar) with variable rather than fixed output. This makes it the correct choice for machines with higher or more variable hydraulic demand — medium-capacity tippers and certain forklift classes — rather than a simple upgrade of the same architecture.

Real-World Service Life
Like the 4623, a well-maintained 72400 typically delivers 150,000-250,000 operating cycles with clean hydraulic fluid and regular filter changes — but given the higher pressure and variable-displacement mechanism, contamination-related wear can progress faster than in a simpler gear pump if maintenance is neglected.
What Our Quality Process Covers
Piston & Swashplate AssemblyMeasured against Eaton tolerance and replaced where wear exceeds spec — a genuinely more involved process than gear pump service.
Variable Displacement ControlTested for accurate, responsive output control across the pump's variable range.
Shaft Seal & All O-ringsReplaced as standard on every unit.
Bench Pressure & Flow TestVerified at 250 bar rated pressure, output documented on the written test report.

FAQs — Eaton 72400 Pump
Can I fit a 72400 in place of a 4623 for more power?
Not directly — these are different pump architectures (piston vs gear) with different mounting and control requirements. Your machine's circuit is designed around one or the other; check with us before assuming a swap is possible.
Why does my tipper truck need the 72400 instead of the more common 4623?
Larger tipper bodies (12-16 cubic metre vs the 4623's 8-12 cubic metre range) need more hydraulic capacity and often benefit from the 72400's variable output — the correct pump depends on your specific body size and manufacturer's original specification.
